MSI R9 290 4gb....UPGRADE?

Been out of the loop for a bit (divorce, new house, etc. ugggg) . Everything lining out now, but I need a bit of help. I want to give my son a new video card for his (my pc actually in sig) gaming rig. As noted in the subject, it's an R9 290. I have $500 to spend for his graduation gift, so...is there a faster card than my current one for that amount of cash? His primary game on the pc right now is Escape from Tarkov.
